Specification of Letters Patent.

Application filed January 12, 1916. Serial No. 71,629.

hitherto to apply the sheets to the backing material, cloth, paper orthe like by'the ordinary method of brushing and pasting, usually on aflat surface. Where paper is used to back the lithograph, this involvesconsiderable difliculty because it is not easy to handle large sizedsheets on a horizontal surface and on a vertical surface any attempt toshift the back or the lithograph or both together, is difficult owing tothe suction of the wet fabric on the supporting surface. It isfurthermore necessary, in order to provide a smooth mount, that thebacking material used should be moistened and allowed to swell so thatwhen the applied pasted lithograph unites firmly with the backing, andthe paste dries out, the backing and the sheet shrink= evenly andthereby avoid wrinkling.

This invention relates to a system. for mounting lithographs, posters orthe like, whereby the operation may be carried on continuously, wherebythe backing ofpaper is moistened sufficiently and allowed to swell.

properly before the pasted lithograph is ap-.

plied and whereby the margins of thefinished product are reinforced,together with other features that obtain perfectly smooth and suitablemounts.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, p 1 Figure 1 is a View in side elevation'o-f mechanismfor mounting photo-lithographs according to the method herein described,and forming itself a part of the invention;

Fig. 2 is a View in front elevation thereof; Figs. 3 and 1 are views indetail of a finished mount; Figs. 5 and 6 are views in'detail ofamarginal folder; 1

Fig. 7 is a view in detail of a drying stack;

Fig. 8 is a view in detail of a spreader;

Fig. 9 is a View in detail of margin pasting rolls; and

Fig. 10 is a View in detail of a mounting strip and support.

As herein indicated, a main frame 1 of suitable material and design tocombine strength and rigidity with lightness has bearings 2 fora spindle3 of a stock roll of paper or like fabric that is intended for backinglithographs or the like, the bearings being arranged adjacent amoistening tank 4: with a guide roll 5 therein aroundwhich the paper isdrawn as indicated through the contents of the tank. At the front of theframe there is an upright perforated or foraminous screen 6 with guiderolls 7 and 8 at the top and bottom, to the latter of which the paper isled over a series of rolls 9, 10 and 11 so disposed in the frame of themachine that by the time the paper has reached the screen, it has becomefully expandedby the action of the water through which it is drawn. Thearrangement of this train of rolls is of course immaterial provided thepaper is given time to take up the water and become thoroughly expandedwhen it reaches the screen. An inclined bed 12, likewise of perforatedmaterial or screen,

leads from the upper roll 7 to a horizontal traveling track or endlessbelt carrier 13 or even a flat table whereby the paper with the appliedmount is moved along readily for beingcut. Preferably, an idler 14 restson the upper roller, the bearings permitting vertical movement, so thatthe weight of the idler assists in drawing the paper over the roller 7.l a

To aid the movement of the wetted paper, to which lithographs are pastedas the strip of backing travels up the screen, there may be endlesscarrier belts 15 passing over the upper roll 7 and a similar idler 16 atthe lower end of the incline, the upper roll 7 being peripherallychanneled to receive the i belts and present a flush face for the paper.

The train of rolls over which the paper passes, and the cylinders 7 and8, are either operated by hand, or preferably as herein indicated, by asuitable motor 17 with such .1

driving gear between theparts asgive them the speed to carry the paperalong. This mechanism which is indicated diagrammatically herein at 18may, of course, take any preferred form. 1

As the paper passes over the last roll in the intermediate train betweenthe feed cylinder or paper roll and the roll 8,"it' encounters aspreader19 which, consists preferably of divergent arms faced withfeltor other like material whereby the paperiseX- panded or freed fromlongitudinal wrinkles andmade to'run ontotlie roll 8 inasmooth andlaterally expandedeondition As the. paper passes up over the screens theperforati nsofwhich admit air behind; the wet layer, so th at he paperdoes notycleayefto .the screen. butsli desfreely there oyerfthe parts ofthe litl'iographs may be I pasted thereto manually, one; other.

I 'fAs the paper back andapplied'lithographs pass slowly up the s'creent'he extended margins each encounter a folding device at 31, the detailsof'which are indicatedin Figs. 5 and. 6.
